An issue was discovered in Cloudera Manager 5.x before 5.16.2, 6.0.x before 6.0.2, and 6.1.x before 6.1.1. Malicious impala queries can result in Cross Site Scripting (XSS) when viewed within this product.
The keystore password for the Spark History Server may be exposed in unsecured files under the /var/run/cloudera-scm-agent directory managed by Cloudera Manager. The keystore file itself is not exposed.
An issue was discovered in Cloudera Manager 5.x through 5.15.0. One type of page in Cloudera Manager uses a 'returnUrl' parameter to redirect the user to another page in Cloudera Manager once a wizard is completed. The validity of this parameter was not checked. As a result, the user could be automatically redirected to an attacker's external site or perform a malicious JavaScript function that results in cross-site scripting (XSS). This was fixed by not allowing any value in the returnUrl parameter with patterns such as http://, https://, //, or javascript. The only exceptions to this rule are the SAML Login/Logout URLs, which remain supported since they are explicitly configured and they are not passed via the returnUrl parameter.
An issue was discovered in Cloudera Manager before 5.13.4, 5.14.x before 5.14.4, and 5.15.x before 5.15.1. A read-only user can access sensitive cluster information.
